The embodiment of the invention discloses a two-dimensional air inlet test device, relating to a mid-range supersonic speed air-to-surface missile design technology, which can solve the problem that the thermal load under heat and force combined action subjected to the structure is not true. A gas generator is installed at one end near the outlet of a two-dimensional air inlet of a missile body simulation piece, a partition structure is arranged on the edge of the port of the two-dimensional air inlet, and the partition structure communicates the outlet of the gas generator and the outlet of the two-dimensional air inlet. The outlet of the gas generator and the other end of the missile body simulation piece are sealed, fuel gas generated by the gas generator enters the two-dimensional airinlet for combustion, the two-dimensional air inlet is connected to at least one actuator cylinder, and a quartz lamp heater is placed outside the two-dimensional air inlet for heating the two-dimensional air inlet exposed on the outside of the missile body. The device is mainly used for inner heating and outer heating and static force combined testing in the two-dimensional air inlet.
Description
technical field [0001] The invention relates to the technical field of medium-range supersonic air-to-surface missile design, in particular to a binary inlet test device. Background technique [0002] The combined mechanical and thermal test of the binary inlet of the aircraft is an important part of the design and strength assessment test of the binary inlet, and has been valued by the designers. The three exposed surfaces and the internal compression surface of the binary inlet act on the high temperature generated by the flow channel, and one side acts on the high temperature generated by the aerodynamic heating. The whole body bears the aerodynamic load and transmits the load to the projectile through the connecting joint. For a long time, the mechanical-thermal joint test of the binary inlet adopts the heating method of quartz lamps. Due to the limitation of the size of the inlet structure, it can only heat the inlet structure exposed on the outside of the projectile, c...
